Warning
1. The mask does not eliminate the risk of contracting any disease or infection.
Go ahead let the hate posts begin...
"but I'm not sick" you say... well I don't know you, and I don't know that, so when you are out in public you wear a mask to protect me and my mom, and my dad, and my kids from you, and because you don't know me, and you don't know if I'm sick, I wear a mask to protect you and yours.
edit - I didn't downvote your post, I'd like people to learn

When the situation is back to normal, hopefully they will remove all the return restrictions.
Before Covid-19 when we can buy Surgical Masks from CVS, Target, etc, each box usually mentioned the ASTM standard it meet right outside the box.
https://www.halyardheal
In the United States, they must respect ASTM standards which have three levels of protection (from low risk of exposure to fluids to high risk of exposure to fluids).
BFE = Bacterial Filtration
PFE = Particulate Filtration
In Europe, they must comply with the European standard EN 14683, which has 3 levels of bacterial filtration efficiency (BFE1, BFE2, Type R).
Hopefully as face mask become more available, people would start posting face mask deal that actually meet the ASTM, Europe, or other standard at reasonable price.
================
Also Droplets from human speech can last in air for more than 8 minutes, study from Penn says
https://www.pnas.org/content/117/22/11875
Speech droplets generated by asymptomatic carriers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are increasingly considered to be a likely mode of disease transmission. Highly sensitive laser light scattering observations have revealed that loud speech can emit thousands of oral fluid droplets per second. In a closed, stagnant air environment, they disappear from the window of view with time constants in the range of 8 to 14 min, which corresponds to droplet nuclei of ca. 4 μm diameter, or 12- to 21-μm droplets prior to dehydration. These observations confirm that there is a substantial probability that normal speaking causes airborne virus transmission in confined environments.
